I'm guessing it's male, because of the hump on his head like a Flowerhorn.
I wouldn't rule out the fact that this might be a female. I have a female, similar in size, that has a hump similar to the fish in your photo at all times, but gets exaggerated nearly overnight when she goes into egg laying mode. This happens every couple weeks even though there has never been a fish in the tank she could mate with.
